The sum of two numbers is 35. Their difference is 3. Find the numbers
IgorLugansk [536]

Answer:

19 and 16

Step-by-step explanation:

Let x and y be the two numbers

x+y = 35

x-y =3

Add the two equations together

x+y = 35

x-y =3

---------------

2x = 38

Divide by 2

2x/2 = 38/2

x = 19

Solve for y

x-y = 3

19-y = 3

Subtract 19 from each side

19-19 -y = 3-19

-y = -16

y =16

xenn [34]
Calculate the circumference of the circle, and multiply it by 23.

C = pi * d

C = 3.14 * 63 ft =197.82 ft

23 * C = 23 * 197.82 ft = 4549.86 ft
